Glioblastoma multiforme (GBM) exhibits the most malignant brain tumor with very poor prognosis. MicroRNAs (miRNAs) are regulatory factors that can downregulate the expression of multiple genes. Several miRNAs acting as tumor‐suppressor genes have been identified so far. The delivery of miRNA by mesenchymal stem cell (MSC) due to their ability to specifically target tumors is a new, hopeful therapeutic approach for glioblastoma. The objective of our study is the investigation of the effect of lentivirus‐mediated microRNA‐4731 (miR‐4731) genetic manipulated adipose‐derived (AD)‐MSC on GBM. The downregulation of miR‐4731 in human GBM tumor was detected using the GEO dataset. To evaluate the function of miR‐4731, we overexpressed miR‐4731 using lentiviral vectors in U‐87 and U‐251 GBM cell lines. The effects of miR‐4731 on cell proliferation and cell cycle of glioma cells were analyzed by wound test and flow‐cytometry assay. miR‐4731 inhibited the proliferation of GBM cancer cells. Coculturing was used to study the antiproliferative effect of miR‐4731‐AD‐MSCs on GBM cell lines. Direct and indirect coculture of GBM cell lines with miR‐4731‐AD‐MSCs induced cell cycle arrest and apoptosis. Our findings suggest that AD‐MSCs expressing miR‐4731 have favorable antitumor characteristics and should be further explored in future glioma therapy.
